It's not supposed to be a real move.

You're doing it wrong; it's not that simple. To do it correctly, the dude has to be up in the air, and you need to use your arms to whip him violently to the ground. Like I said, this is not a real judo technique. Disregard the demo vid I took and the one replay that looked like a hip throw. I'll attach two true roux whips once again.
